/**
 * `subscribe({ sink, source })` is sugar for `source.subscribe(sink)`.
 *
 * When programming, you generally declare a variable in terms of an expression:
 *
 *     const result = 1 + 2 + 3;
 *
 * You declare the output you are affecting and then the expression that defines
 * it.  Observables typically invert this flow:
 *
 *     `1$.addedBy(2).addedBy(3).subscribe(result$);`
 *
 * `subscribe({ sink, source: input$ })` corrects this, making declarations
 * easier to read by identifying the output before the expression that writes to
 * it:
 *
 *     subscribe({
 *       sink: result$,
 *       source: 1$.addedBy(2).addedBy(3)
 *     });
